Many thanks. I had checked these pages out - the first was particularly useful. I had two issues though: firstly, it wasn't clear how they'd arrived at the evaporation coefficient. Secondly, it wasn't clear how I should calculate the humidity ratios. If anyone can point me in the right direction...
Can anyone provide me with a reliable formular for calculating evaporation losses from an indoor swimming pool when I have the following information/data:
size of pool
pool temp
pool hall temp
pool hall % saturation
vapour pressure at pool surface
vapour pressure in pool hall
air velocity at...
